Learn to work with the Docker and Docker containers for distribution of your applications.Learn to work with the Docker and Docker containers for distribution of your applications.
Docker is a software package which is used for operating-system-level virtualization. To run software on the Docker a special package called containers are created which includes all the libraries and OS libraries to run the packaged software. Then this software package (Docker container) is run by Docker software tool. The Docker is light-weight because it uses the kernel of the host system to run the container. It is similar to virtual images minus the operating system, means container does not contain the OS kernel. So, if you have multiple containers you can run by a single operating-system kernel and this makes it must lightweight than virtual machines.
The Docker was developed by a company called Docker, Inc. and first deployed in 2013. Since then Docker is growing fast in the software industry and it is being used in production environments. The Docker popularity is growing very fast and most of the new generation software package is being run on Docker in the production environment.
As explained above, Docker is a software tool for operating-system-level virtualization and this is used for distributing applications along with all its dependencies. This is popular tool for creating, deploying and running applications in a distributed environment. For example you can create a Docker image to run MySQL server and then deploy this on Docker runtime. It allows very convenient way to distribute packaged applications.
In this tutorial we are going to explore Docker and Docker Compose tools. Tutorials here will help you in learning this fantastic tool for application distribution.
Here are the tutorials for learning Docker from beginning.
